normaly the stick position represents a servo position. For camera control i need something different:
The more you push the stick, the faster the servo should change its position. If the stick is back in neutral, the servo should keep its last position.

First mix holds the channel
2nd mix adds a bit of the rudder stick in, more stick quicker moving.
3rd and 4th mixes stop the channel value going past 100%, otherwise it would and then would not move back immediately. (Limits stop the servo output, not the channel value)

Play with the 2% in the second mix for different speed of movement. If it is too much, you will need to use another channel, e.g.
CH15: +20% RUD
then use CH15 instead of RUD in the 2nd mix. 2% of 20% is 0.4%.

The difficult we do immediately,
The impossible takes a little longer!

I just tried this on taranis, it works but at either end it bounces back and forth to 84 and 100 if I hold the stick at end and any time I let go it can be at anything from 84 to 99.
This was using kilrah s version

Thanks, that worked fine in opentx.
on the taranis it is too fast, only the slightest of touches on the stick sends the servo to full deflection quite quickly and so very small movements are needed.
I will play about and see if I can make it work better.
Kirah version works at a nice pace.

OK ,
I figured out a better version, based on Mikes,
this works much better on tx, looks very slow on opentx but where it matters on tx it is fine.
It does bounce a little at either end but only by .1% or so.
It uses another channel utulising 500 travel and mixing it down with 20%.

wanted to quickly post my configuration which is based on the ones above.

Background:
CH6 controls my Gimbal (Gimbal FW is set to position mode = gimbal will tilt and stop based on the position of the stick/side lever).
As this makes filming flyovers rather difficult due to the need to smoothly move the stick in accordance with the speed of the vehicle, I was looking for an option to toggle between both modes.

Thanks guys for providing the solution above (Mike, the last solution you posted above did not work for me as the movement is not smooth - it jumps in accordance with the steps due to the delay I believe).

Hello, can I program something like this direct on a taranis X9E with the original firmware?
I have some 1/87 scale models rc conversions, and this way to control a servo is perfect for cranes and excavators. Thanks in advance.

I think he was asking how to do it as well?
I don't remenber how to, but I think Mike made an example a few years ago, but is was for Er9x/ErSky9x.. I think it should work the same in OpenTX.
I will look at some examples I have been gathering all over the years to see if I have this one. Unless Mike post it before of course..

Thank you very much, I have a very very limited space in my models. Normally I use planetary gear motors for almost all the movements I need, but this motors are very expensive and requires an extra ESC for motor(more space). Many times a cheap micro servo can do the work, but my problem is control that like a real machine. Here you can see my last crane truck over my X9E...https://youtu.be/4j5C2Bn8CAw
